Top Deflection Studies - Ovation Acoustic Frequency Response Test Record - Unit 1119-4 'A' Bracing

1974 US 1 pages

This is a technical test record document from Ovation Instruments dated October 31, 1974, showing an acoustic frequency response graph for guitar unit 1119-4 with 'A' bracing configuration. The graph plots decibel levels (ranging from +20 to -40 dB) against frequency (approximately 41 Hz to 9397 Hz), with notable resonance peaks around 130-165 Hz reaching +13 dB and around 196 Hz reaching +11 dB. This appears to be an internal quality control or research document (Test Record No. 47) rather than a consumer catalog or brochure.
